GRAIN `ELEVATOR AND DUMP.

SPECIFICATION forming pari'. of `Letters Patent No. 665,216, datedJanuary 1, 1901. Application filed June 28, 1900.4 Serial No. 21,924.tNo model.)

T0 all whom it may concern,.-

Be it known that I, SCOTT HAR'rsocK, a citizen of. the United States,residing at Henry, in the county of Marshall and State of Illinois, haveinvented a new and useful Grain Elevator and Dump, of which thefollowing is a specification.

My invention is an improved grain dump and elevator adapted for use inunloading grain from wagons and elevating the same, particularly inplaces at which the amount of work to be done will not warrant' the useof a steam-engine or other costly power plant for operating theelevator.

My invention consists in the peculiar construction and combination ofdevices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of a graindump and elevator constructed in accordance with my invention. Fig. 2 isa vertical longitudinal sectional view of the same. View of the same.Fig. 4 is a sectional view taken on the line a a. of Fig. 3. Fig.l 5 isa detail sectional view of the elevator. Fig. 6 is a detail sectionalview of thedump mechanism, taken on the line b b of Fig. 3. is a similarview taken on the line c c of Fig. 3. Figs. 8 and 9 are detail views ofAmembers of the endless elevator. Y l

The dump-platform A is supported by a frame 2, which is mounted onsupportingwheels 3, the whole constituting a truck. Atransversely-disposed trough 4 is near one end of the platform, which Iwill call the front end thereof. In the said trough is ahorizontally-disposed conveyer 5, comprising an endless travelingelement 6, which -is .made up of endless belts or chains 7 andtransverselydisposed sections 8, which connect said endless belts orchains, and driving and supporting rollers 9 10, on which the endlesstraveling element operates inthe direction shown by the arrows in Fig. 4to convey grain which is dumped thereon tov the'elevator B at one sideof the platform. The roller 9 `has an extended shaft 11, which isprovided at its front end with a power-pulley 12, driven from apower-pulley 13 on a shaft 14 by an endless belt 15. The said shaft 14is journaled in bearings 16 on the outer side of the frame of the Fig. 3is a top plan Fig. 7

elevator at the base thereof, and said shaft at its rear end is providedwith a miter gearwheel17. The elevator is of the endless travel` ingtype and has the usual inclined trunk or casing' 18, and the endlesstraveling element 19 of the elevator is disposed in the said trunk orcasing and supported and actuated by rollers 2021. The latter, which isat the lower end of the trunk or casing, has an extended shaft 22,provided with a miter-gear 23, that engages miter-gear 17 ,and saidshaftis further provided with a power-pulley 24.

It will be understood from the foregoing description and by reference tothe drawings that the conveyer and elevator are operated in unison, theconveyer serving to carry the grain to the lower end of the elevatortrunk or casing and the endless traveling element of the elevatorserving to elevate the grain.

The endless traveling element of the elevator is composed ofbucket-sections 25, each of which has a right-angled ledge 26 on oneside, and the inner sides of said buckets, at the edges thereof, arecurved, as at-27. The said bucket-sections are connected together inseries by flexible cords 28. In passing `over a Vroller at the upper orlower end of the elevator-trunk the fiexible connecting-cords 28 adaptthe bucket-sections to change theirl positions relatively to conform tothe shape of the rollers,and the curved edges 27 of the respectivebucket-sections coact as the bucketsections pass around the saidrollers, the said curved edges 27 enabling the bucket-sections to remainin contact with each other at all times, even when changing thedirection of their movement. ,Hence the endless traveling elevatingelement is adapted to discharge all the grain elevated thereby `throughthe spout 29 ofthe trunk or casing 18 without dropping any ofthe grainbetween the bucketsections which are disposed and in the act of passingon the upper roller 20.

The conveyer 5 is adapted to be closed by a trap-30 on the upper side ofthe'trough 4, the 'said trap being hinged at one side on arock-shaft'3l. Said rock-shaft is provided on the side of the platformopposite the elevator with a rock-arm 32. 7A hand-lever 33 is disposedon one side of the platform and fulcrumed to the frame thereof at itslowe'r end, as at 34. A pitman 35 connects'the said IOO hand-lever withthe rockarm 32, and it will be understood that the trap-door 30 may beoperated by the lever33 in such manner as to cover or uncover theconveyer 5, as may be required. A segment-plate 36 on one side of theplatform coactswith a spring-pressed dog 37 of the usual form, withwhich the handlever 33 is provided, to secure the latter at any desiredposition.

In longitudinally-disposed openings 38 in the sides of the platform aredump-bars 39, the latter having centrally-disposed pivotal supports 40,whereby the said dump-bars are adapted to be disposed in the same planewith the platform or to be inclined to the position indicated in Figs. 2and 6 of the drawings for the purpose of lowering the rear end of awagon on the platform, the hind wheels of which are on the front ends ofthe dum p-bars, in such manner as to incline the wagon-bed to such anextent as to cause the same to discharge the load of grain therefrom bygravity into the trough 4 and onto the conveyer 5. The platform isprovided on its front end with a skid 4l,forming an inclined frame, upwhich the wagon may be driven, so as to dispose the same on the platformwith its rear Wheels resting on the front portions of the dumpbars.While the wagon is being thus disposed on the platform, the dump-barsare in a horizontal position and supported in such position byeccentrics 42 on ashaft 43, which is journaled in bearings 44, securedto the under sides ofthe dump-bars at a suitable distance from the frontends thereof. The said shaft 43 is a rock-shaft and is provided at oneend with a rock-arm 45, which is connected by a pitman 46 to ahand-lever 47. Said hand-lever is in all respects similar to the lever33, and it will be understood that by means of said hand-lever, saidpitman, and said rock-arm the rock-shaft may be partly turned in eitherdirection and caused to impart partial rotary motion to the eccentrics42, whereby the front ends of the dump-bars may be lowered to theposition shown in Figs. 2 and 6, so as to dump the load from the wagon.The eccentrics 42 are supported and operate upon suitable side bars 48,which form a portion of the frame that supports the platform.

I will now describe my improved treadpower C, which is operated by theteam that draws the wagon and furnishes power to operate the endlessconveyer 5 and the elevator B. A frame 49 of suitable construction sup-A ports the tread-power and is provided with supporting wheels orrollers 50, whereby it is converted into a truck which may be readilydrawn from place to place. The frame 5l carries the endless tread-apron52, which operates on rollers 53 54 at the inner and outer end of frame52. The said frame 52 is pivotally mounted at its inner end betweenvertical standards 55, which rise from the inner end of truck-frame 49.A rock-shaft 56 is journaled in the outer or rear end of frame 52, andkeyed to said shaft are eccentrics 57, which operate on the frame 49,support the rear end of the frame 52, and may be turned by therock-shaft 56 to raise the tread-power to the inclined position (shownin Fig. 2) or to lower the same to the horizontal position. (Shown inFig. l.) The rock-shaft 56 may be thus turned by a pitman 58, which isconnected to one of the eccentrics, as at 59, and is operated by ahand-lever 60, which is fulcrumed on one of the standards 55 and islocked in the required position by a coacting segment-plate 6l and dog62. p

A combined skid and gate 63 is hinged to the rear side of thetread-power frame and when turned up to the position shown in Fig. 2forms a gate or bar to stop the team attached to the wagon which is tobe unladen, and when turned downward to the position indicated in Figs.l and 3 of the drawings forms an inclined plane to facilitate the passage of the wagon from the tread-power. The said combined skid and gateis operative by a pitman 64 and hand-lever 65, the latter having a dog66, which coacts with a segmentplate 67 to secure the gate in theposition shown in Fig. 2.

I will now describe means for transmitting power from the tread-power tothe endless conveyerandelevator. Apower-roller68has its shaft journaledin bearings in theframe 62, and said power-roller is disposed aboutmidway between the rollers 53 54 and is engaged by the upper and lowerleads of the tread-apron and rotated by frictional contact therewith.The shaft 69 of power-roller 68 is extended at one end and provided witha power-pulley 70, which is connected to the power-pulley 24 on shaft 22by an endless power-belt 71 when the platform-frame and tread-bar frameare secured together end to end, as shown herein. Hooks 72 or othersuitable devices may be employed for thus securing the said framestogether. The shaft 69 is provided also with a friction-pulley 69, whichis adapted to be engaged by a frictionbar 73 to stop the tread-powerwhen it is desired to discontinue the operation thereof and of theconveyer and elevator. A suitable hand-lever 74 is employed, which ismounted on the frame 49 and is connected to the friction-bar 73 by apitman 75, the function of this hand-lever and said pitman being tooperate the said friction-bar, as will be linderstood.

Having thus described my invention, I claiml. A grain dump or elevatorhaving a platform onto which a wagon may be driven, an elevator, aconveyer to discharge the load from the wagon to said elevator, incombination with a horse-power at one end of the platform, adapted to beoperated by the horse or horses attached to the wagon, connectionsbetween said horse-power and elevator, whereby the latter may be driven,said connections including a shaft rotated by the horsepower, a

is provided, an operating-lever and connections between the same `amdsaid shaft, substantially as described.

In testimony that I claim the foregoing as r 5 my own I have heretoaffixed my signature in the presence of two witnesses.
